Top Gear was even more impressed with the Venom’s acceleration than with the top speed — from 120 mph to 220 mph in just under 10 seconds.

“At the very top end, there was a little wandering, but hey, we're going 270mph!" Smith told Top Gear. "It was still pulling. If we could run on an eight-mile oval, we could go faster than that."

Company owner John Hennessey told Top Gear that he thought the car could have hit 275 or even 280 if they’d had the room to make the run.

“Looking at the rate of acceleration, we’re still pulling around 1 mph per second at 270 mph,” he told Top Gear. He was happy with the test results, he added. “Since the inception of the Venom GT, it's been a dream of ours to build the fastest car. There are lots of different definitions, different metrics, but for us, when people talk about being the fastest, it's about being the absolute fastest. So it was a good day. We achieved the goal. No other road car has broken 270mph."
